This application is related to, commonly assigned, U.S. Provisional Patent Application Ser. No. 63/203,140, entitled “FACILITATING AND PROVISIONING CUSTOMER BROADBAND TRANSPORT SERVICE”, filed on Jul. 9, 2021, which is hereby incorporated by reference in its entirety.

BACKGROUND

Subscribers of digital communications at a residence or business (the “service location”) have a number of options based on the connection options available at the service location. Traditional communications employ cable, fiber, wireless, and plain-old-telephone connection options. Each subscriber service provider has challenges deploying service to new subscribers and existing subscribers who request new service.

Cable and fiber networks require a cable and/or fiber drop at the service location to establish a digital connection. Cellular and satellite networks require wireless equipment for digital access. Conventional telephone lines can be used with modems supporting DSL (digital subscriber loop) communications. However, each service typically involves substantial installation and programming to ensure the subscriber has a proper connection.

Conventional wireless network services suffer from the issues commonly found with wireless networks, such as signal dropout, fading, interference, and relatively modest uplink transmission rates. Different networks may offer vastly different service connections depending on the connection options at a particular location. Conventional digital cable or optical fiber systems provide relatively fast communications but typically require a large capital investment associated with installing and maintaining cable and fiber networks and provisioning services to users.

Conventional plain telephone lines typically supported substantially lower communications speeds than cable systems and may employ DSL (digital subscriber loop) communications featuring additional overhead for provisioning access both by virtue of equipment and establishing services to users.

These services typically required a technician to visit the location to install necessary equipment and to ensure signal strength and connections were adequate for the desired service. Accordingly, such technician visits involved service delay to coordinate with the subscriber and for technician personnel to be deployed to ensure connection. In addition, the necessary equipment typically requires direct access to an electrical outlet to provide power to the devices.

There is a need in the art for a system for easily and quickly deploying and provisioning high speed digital communications to users at residential and commercial locations that may or may not have direct access to an electrical outlet. Such a system should be easy and efficient to set up and use. Such a system should provide the subscriber with high speed digital communications without a power outlet or when power is unavailable, preferably minimizing or reducing the delays, difficulties, and cost associated with scheduling a technician to visit the service location to establish service.

SUMMARY

The present subject matter provides an apparatus and method for providing bidirectional power feed digital communication devices for service locations. The device further includes a bidirectional power feed connection configured to receive power from or provide power to an external device via a multiple conductors for digital communications, such as radio frequency (RF) modulation communications over multiple conductors between the digital communication port and the external device.

This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims. The scope of the present invention is defined by the appended claims and their legal equivalents.

Modules, Components, and Logic

Certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code embodied on a machine-readable medium) or hardware modules. A “hardware module” is a tangible unit capable of performing certain operations and may be configured or arranged in a certain physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.

In some embodiments, a hardware module may be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware module may include dedicated circuitry or logic that is permanently configured to perform certain operations. For example, a hardware module may be a special-purpose processor, such as a Field-Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). A hardware module may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, a hardware module may include software executed by a general-purpose processor or other programmable processor. Once configured by such software, hardware modules become specific machines (or specific components of a machine) uniquely tailored to perform the configured functions and are no longer general-purpose processors. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.

Accordingly, the phrase “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. As used herein, “hardware-implemented module” refers to a hardware module. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where a hardware module comprises a general-purpose processor configured by software to become a special-purpose processor, the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware modules) at different times. Software accordingly configures a particular processor or processors, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.

Hardware modules can provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).

The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions described herein. As used herein, “processor-implemented module” refers to a hardware module implemented using one or more processors.

Similarly, the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented modules. Moreover, the one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an Application Program Interface (API)).

The performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors or processor-implemented modules may be distributed across a number of geographic locations.

Machine and Software Architecture

The modules, methods, applications and so forth described in conjunction with FIGS. 1-22 are implemented in some embodiments in the context of a machine and an associated software architecture. The sections below describe a representative architecture that is suitable for use with the disclosed embodiments.

Software architectures are used in conjunction with hardware architectures to create devices and machines tailored to particular purposes. For example, a particular hardware architecture coupled with a particular software architecture will create a mobile device, such as a mobile phone, tablet device, or so forth. A slightly different hardware and software architecture may yield a smart device for use in the “internet of things.” While yet another combination produces a server computer for use within a cloud computing architecture. Not all combinations of such software and hardware architectures are presented here as those of skill in the art can readily understand how to implement the invention in different contexts from the disclosure contained herein.

Example Machine Architecture and Machine-Readable Medium

FIG. 23 is a block diagram illustrating components of a machine 2300, according to some example embodiments, able to read instructions from a machine-readable medium (e.g., a machine-readable storage medium) and perform any one or more of the methodologies discussed herein. Specifically, FIG. 23 shows a diagrammatic representation of the machine 2300 in the example form of a computer system, within which instructions 2316 (e.g., software, a program, an application, an applet, an app, or other executable code) for causing the machine 2300 to perform any one or more of the methodologies discussed herein may be executed. For example the instructions may cause the machine to execute the flow diagrams of FIGS. 8-11 . Additionally, or alternatively, the instructions may implement one or more of the devices and/or components of FIGS. 1-7 and 12 . The instructions transform the general, non-programmed machine into a particular machine programmed to carry out the described and illustrated functions in the manner described. In alternative embodiments, the machine 2300 operates as a standalone device or may be coupled (e.g., networked) to other machines. In a networked deployment, the machine 2300 may operate in the capacity of a server machine or a client machine in a server-client network environment, or as a peer machine in a peer-to-peer (or distributed) network environment. The machine 2300 may comprise, but not be limited to, a server computer, a client computer, a personal computer (PC), a tablet computer, a laptop computer, a netbook, a personal digital assistant (PDA), or any machine capable of executing the instructions 2316, sequentially or otherwise, that specify actions to be taken by machine 2300. Further, while only a single machine 2300 is illustrated, the term “machine” shall also be taken to include a collection of machines 2300 that individually or jointly execute the instructions 2316 to perform any one or more of the methodologies discussed herein.

The machine 2300 may include processors 2310, memory 2330, and I/O components 2350, which may be configured to communicate with each other such as via a bus 2302. In an example embodiment, the processors 2310 (e.g., a Central Processing Unit (CPU), a Reduced Instruction Set Computing (RISC) processor, a Complex Instruction Set Computing (CISC) processor, a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Radio-Frequency Integrated Circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, processor 2312 and processor 2314 that may execute instructions 2316. The term “processor” is intended to include multi-core processor that may comprise two or more independent processors (sometimes referred to as “cores”) that may execute instructions contemporaneously. Although FIG. 23 shows multiple processors, the machine 2300 may include a single processor with a single core, a single processor with multiple cores (e.g., a multi-core process), multiple processors with a single core, multiple processors with multiples cores, or any combination thereof.

The memory/storage 2330 may include a memory 2332, such as a main memory, or other memory storage, and a storage unit 2336, both accessible to the processors 2310 such as via the bus 2302. The storage unit 2336 and memory 2332 store the instructions 2316 embodying any one or more of the methodologies or functions described herein. The instructions 2316 may also reside, completely or partially, within the memory 2332, within the storage unit 2336, within at least one of the processors 2310 (e.g., within the processor's cache memory), or any suitable combination thereof, during execution thereof by the machine 2300. Accordingly, the memory 2332, the storage unit 2336, and the memory of processors 2310 are examples of machine-readable media.

As used herein, “machine-readable medium” means a device able to store instructions and data temporarily or permanently and may include, but is not be limited to, random-access memory (RAM), read-only memory (ROM), buffer memory, flash memory, optical media, magnetic media, cache memory, other types of storage (e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/or any suitable combination thereof. The term “machine-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) able to store instructions 2316. The term “machine-readable medium” shall also be taken to include any medium, or combination of multiple media, that is capable of storing instructions (e.g., instructions 2316) for execution by a machine (e.g., machine 2300), such that the instructions, when executed by one or more processors of the machine 2300 (e.g., processors 2310), cause the machine 2300 to perform any one or more of the methodologies described herein. Accordingly, a “machine-readable medium” refers to a single storage apparatus or device, as well as “cloud-based” storage systems or storage networks that include multiple storage apparatus or devices. The term “machine-readable medium” excludes signals per se.

The I/O components 2350 may include a wide variety of components to receive input, provide output, produce output, transmit information, exchange information, capture measurements, and so on. The specific I/O components 2350 that are included in a particular machine will depend on the type of machine. For example, portable machines such as mobile phones will likely include a touch input device or other such input mechanisms, while a headless server machine will likely not include such a touch input device. It will be appreciated that the I/O components 2350 may include many other components that are not shown in FIG. 23 . The I/O components 2350 are grouped according to functionality merely for simplifying the following discussion and the grouping is in no way limiting. In various example embodiments, the 1/O components 2350 may include output components 2352 and input components 2354. The output components 2352 may include visual components (e.g., a display such as a plasma display panel (PDP), a light emitting diode (LED) display, a liquid crystal display (LCD), a projector, or a cathode ray tube (CRT)), acoustic components (e.g., speakers), haptic components (e.g., a vibratory motor, resistance mechanisms), other signal generators, and so forth. The input components 2354 may include alphanumeric input components (e.g., a keyboard, a touch screen configured to receive alphanumeric input, a photo-optical keyboard, or other alphanumeric input components), point based input components (e.g., a mouse, a touchpad, a trackball, a joystick, a motion sensor, or other pointing instrument), tactile input components (e.g., a physical button, a touch screen that provides location and/or force of touches or touch gestures, or other tactile input components), audio input components (e.g., a microphone), and the like.

In further example embodiments, the I/O components 2350 may include biometric components 2356, motion components 2358, environmental components 2360, or position components 2362 among a wide array of other components. For example, the biometric components 2356 may include components to detect expressions (e.g., hand expressions, facial expressions, vocal expressions, body gestures, or eye tracking), measure biosignals (e.g., blood pressure, heart rate, body temperature, perspiration, or brain waves), identify a person (e.g., voice identification, retinal identification, facial identification, fingerprint identification, or electroencephalogram based identification), and the like. The motion components 2358 may include acceleration sensor components (e.g., accelerometer), gravitation sensor components, rotation sensor components (e.g., gyroscope), and so forth. The environmental components 2360 may include, for example, illumination sensor components (e.g., photometer), temperature sensor components (e.g., one or more thermometer that detect ambient temperature), humidity sensor components, pressure sensor components (e.g., barometer), acoustic sensor components (e.g., one or more microphones that detect background noise), proximity sensor components (e.g., infrared sensors that detect nearby objects), gas sensors (e.g., gas detection sensors to detection concentrations of hazardous gases for safety or to measure pollutants in the atmosphere), or other components that may provide indications, measurements, or signals corresponding to a surrounding physical environment.

Communication may be implemented using a wide variety of technologies. The I/O components 2350 may include communication components 2364 operable to couple the machine 2300 to a network 2380 or devices 2370 via coupling 2382 and coupling 2372 respectively.
